There is a record of Hadith Qudsi and there are 40 such ahadeeth. Check
As far as protection is concerned, Allah protects whom He Wills. He wanted to protect the traditions of this beloved and hence we have the Saheeh Books, and the Hadith Qudsi are a part of them.
nowhere. Its just my beleif that they are, because without the traditions Islam is incomplete. The mere fact that they are intact and well preserved and thought of as the second most authentic book, testifies the fact they are being protected by Allah.
My belief is same. Islam is a combination of The Book and The Sunnah of the Prophet:saw:.
If you stick to only one and leave the other alone, you will have confused ideas and your own interpreted Islam in all matters. Like, say.. OK Quran says flesh of swine is haraam, it does not say, bones are haraam as well. I mean some comments are pathetic to say the least.
Another one, oh anything OUT of pig is haraam so the air it breathes in when comes out is haraam for us.
So yeah, Shaheeh ahaadeeth are preserved and it’s only the faith that can be witnessed to it just like believing Quran to be word of God is a matter of faith.
